All snow doesn’t instantly melt above freezing just like all the water in your pot doesn’t instantly evaporate when you turn on the heat. The temperature can rapidly fluctuate up above freezing while there’s still a bunch of snow on the ground, and that takes a while (sometimes days) to melt. Melting is affected by factors like shade, snow depth, etc., so while the picture shows no snow, there might be plenty surrounding it – which could be expected accounting for survivorship bias (namely that the lovebugs are unlikely to be lovin’ on top of a foot of snow).
